4 primary factors, which contribute to the development of acne
- Overproduction of oil in the skin (sebum), under the influence of hormones.
- The insufficient shedding of exfoliated dead skin cells, blocks follicles.
- The blocked follicle can become inflamed and an increase in the growth of bacteria.
- The inflammation in the follicle due to the increase in bacteria results in the rupture of the follicle wall. This inflammation extends into lower layers of the skin causing an acne lesion.
